Diagnosis
Males of this new species similar to those of H. helge Jäger, 2008 ( Jäger 2008: figs 22–38) and H. nyalama Hu & Li, 1987 ( Hu & Li 1987: figs 36–37) in having reduced vRTA, conductor short and almost running straight with acuminate tip, arising from nearly 11-o’clock-position on tegulum, but can be distinguished from the latter by the following characters: (1) embolus arising from 4-o’clock position (arising from 6-o’clock-position in H. helge and H. nyalama ); (2) spermophor with acute angle in distal tegular half, distinctly undulating at retrolateral tegular margin (with obtuse angle in distal tegular half and only slightly curved in proximal half of tegulum in H. helge and H. nyalama ); (3) dRTA distally sharply pointed in retrolateral view (with blunt distal tip in H. helge and H. nyalama ). Males are also similar to those of H. belua Jäger, 2005a , H. cece Jäger, 2014 , H. gyirongensis Hu & Li, 1987 , H. hildebrandti Jäger, 2008 and H. mecistopus Pocock, 1898 in having a similarly shaped spermophor, but can be distinguished by (1) embolus smooth (with basal or sub-basal outgrowth in H. belua and H. hildebrandti ); (2) vRTA simple, flat (with distinct hump in H. belua , H. cece , H. gyirongensis , H. hildebrandti and H. mecistopus ); (3) dRTA simple (with bifurcate tip in H. hildebrandti ). Females of this new species similar to those of H. helge ( Jäger 2008: figs 22–38) in having disk-shaped first windings, glandular pores situated medially on the centre of first windings and an upside-down bottleneck-shaped median septum, but can be distinguished from the latter by the following characters: (1) median septum relatively longer, i.e., ca 3 times as long as wide at its narrowest part (median septum stouter, i.e., at most 2 times as long as wide at its narrowest part in H. helge ); (2) subseptal pocket absent (present and strongly sclerotised in H. helge ); (3) posterior part of IDS kidney-shaped (roughly rounded in H. helge ) ( Figs 5–6 View Fig View Fig ).
Etymology
The specific epithet refers to the type locality of this species, Hainan Island; adjective.

Spination: Palp 131, 101, 2121; Fe I–II 323, III 322, IV 321; Pa I 101, II 100, III–IV 101; Ti I –, II–IV 2126; Mt I –, II 0004, III 1024, IV 3136. Measurements of palp and legs: Palp 7.9 (2.3, 1.2, 1.8, –, 2.6); I – (–, 2.2, –, –,–); II 24.3 (5.9, 2.5, 6.6, 6.9, 2.3); III 18.8 (4.6, 2.3, 4.8, 5.3, 1.5); IV 21.6 (5.3, 2.2, 5.4, 6.6, 2.0). Leg formula: II–IV–III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca 29 intermarginal denticles.
PALP. As in diagnosis. RTA arising distally from tibia, vRTA short with straight distal margin. Cymbium elongated, at least more than twice as long as tegulum. Conductor running almost straight distally, extending slightly beyond cymbial margin, with acuminate tip in ventral view. Embolus filiform and almost running semicircular in ventral view ( Figs 5A View Fig , 6 View Fig ).
COLOURATION IN ETHANOL. Dorsal shield of prosoma yellowish- to slightly reddish-brown, with distinct striae. Fovea distinctly darker. Chelicerae yellowish-brown, with two longitudinal lines of light brown spots. Sternum, labium and gnathocoxae pale yellowish to yellowish-brown, the former with brown margins. Opisthosoma dorsally yellow to yellowish-brown, with two pairs of dots, and a transversal darker marking in front of spinnerets with distal light vertical markings; ventrally yellowish-brown, with irregular markings and a single tiny V-shaped marking close to spinnerets ( Fig. 7A–B View Fig ).

Leg formula: II–IV–I–III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca 31 intermarginal denticles.
COPULATORY ORGAN. As in diagnosis. Epigynal field slightly wider than long, with distinct anterior bands attached to field. Median septum relatively long, narrower at its posterior part, i.e., partly covered by lateral lobes. Median margins of lateral lobes gently curved, in ventral view. First winding of IDS membranous, touching each other medially. Fertilization ducts extending posteriorly distinctly beyond rests of IDS, their tips dorsad ( Fig. 5B–D View Fig ).
